    Abstract:
    The purpose of this study was to assess the immediate and long-term results of incomplete percutaneous transluminal coronary angioplasty (PTCA) in high-risk coronary artery bypass surgery (CABG) patients. 24 pts (male-22, female-2, age - 39-60 years) were divided into 2 groups: I-8 pts with unstable angina pectoris who were definitely not CABG candidates because of very low ejection fraction (LVEF < 24%) and/or diffuse coronary atherosclerosis; II-16 pts selected for CABG only after failed PTCA. From this group 12 pts with unstable angina pectoris and history of myocardial infarction were at higher CABG risk because of LVEF < 40% and diffuse coronary atherosclerosis. 4 pts were poor surgical candidates because of coexistent medical disorders. The strategy of PTCA was to dilate first the most critical (culprit) lesion, responsible for the patient symptoms, usually situated in the artery supplying large area of viable myocardium. We did not achieve: complete revascularization in all our pts (incomplete revascularization by intent). Initial success rate of the PTCA in both groups was 100%. There were no serious complications. During follow-up (6 months--4 yrs) long-term clinical improvement was observed in 7 pts from group I (87.5%) and 14 pts from group II (87.5%). We conclude, that in most pts with unstable angina pectoris and with high-risk of CABG good immediate and long-term results of incomplete PTCA can be achieved.
